Huckert ['5 7] ABSTRACT This invention pertains to swimming pools and particularly those above ground pools or in ground pools in which a flexible liner is supported by a wall. In this invention the upper edge of the liner is retained by a clamping means or a lock-in means which is protected by a coping or deck extension. The support structure is provided with a pair of holes spaced one above the other and adapted to receive an adjusting or retaining pin which permits the coping or an attached deck to be lifted sufficiently from its at rest assembly condition for the liner to be installed or loosened for replacement without disassembly of the coping and attached deck aswell as the support frame of the swim- 18 Claims, 6 Drawing Figures METHOD AND APPARATUS FOR READY INSTALLATION AND RE-INSTALLATION OF A FLEXIBLE LINER FOR SWIMMING POOLS BACKGROUND OF THE INVENTION cover, prefabricated wall sections or panels and with particularly contoured or resilient coping (subclasses l72; 172.12; 172.19 and 172.21).

2. Description of the Prior Art Above ground swimming pools and the like customarily have a support frame which supports a sheet metal wall. This supported wall is usually fixedly attached to the support frame to provide the needed support for the flexible wall of the swimming pool. This basic structure is used for above ground pools even though the pool has been provided with a deck around the upper edge of the pool or the upper edge has been protected by copings and the like. These decks or copings enable the upper edge of the swimming pool to have a protective covering member permitting the user of the pool to enter and leave the pool without engaging or damaging the top of the liner. Since the structure to hold the pool and the liner wall either for round or rectangular pools is assembled prior to the installation of the liner, the adjustment of the liner during the initial installation of the water in the pool or for the replacement of the liner after use, damage and/or normal wear has usually required several workmen to remove the top of the swimming pool assembly and to partially disassemble the pool in order to remove the liner, rearrange an existing liner or replace with a new liner. Such an effort, of course, entails considerable time and expense. The present invention is directed toward means whereby the coping and/or attached deck may be lifted to a degree sufficient to permit the flexible liner to be removed from its support. and with the coping and/or deck in a supported condition the liner may be readily removed, rearranged or reinstalled by one person without the disassembly of the swimming pool structure and support.

SUMMARY OF THE INVENTION above the frame sufficient topermit the liner to be removed without the disassembly of the swimming pool frame.

It is a further object of the invention to provide, and it does provide, a swimming pool frame in which the coping protecting the securing of a flexible liner to the top of a swimming pool frame may be lifted and supported at a distance above the wall which is sufficient to enable the retention of the liner to be removed, rearranged or replaced by one person without the disassembly of the swimming pool support structure. This structure has the upright members and a mating securing member on the coping formed with one member having a pair of vertically disposed holes into which a securing bolt may be shifted from an upper hole to a lower hole and into a cooperating hole in the other member to permit the coping or deck to be movedupward from the side wall of the swimming pool a distance of approximately two inches enabling a workman to easily manipulate the liner and retaining means for removal and reinstallation of the liner. without disassembly of the swimming pool frame and/or deck.

This invention, to be more fully described hereinafter and as seen in the drawings, has its upright supports formed so that the swimming pool frame and support wall may be fully assembled and subsequent thereto the coping and/or deck may be lifted in a vertical manner and in a vertical portion of the support frame there is provided a predeterminedly spaced hole. A bracket carried by the coping has a pair of vertically spaced holes, the upper hole of which is used to secure the coping and/or deck in an edge protecting condition. The other and lower hole supports the coping and/or deck which has beenlifted by an attendant to position the deck two or three inches above its regularly installed position. In this elevated condition the upper edge of the swimming pool wall whereat the flexible liner is retained is exposed enabling a workman to install, remove and re-install or rearrange the securing of the flexible liner to the upper edge of the swimming pool wall.

In addition to the above summary the following disclosure is detailed to insure adequacy and aid in understanding of the invention. This disclosure, however, is not intended to prejudice that purpose of a patent which is to cover each new inventive concept therein no matter how it may later be disguised by variations in form or additions of further improvements. For this reason there has been chosen a specific embodiment of the swimming pool frame and a coping and a deck support as adapted for use with the frame and showing a preferred means for supporting the coping or deck in two elevations.

This specific embodiment and alternate embodiments thereof have been chosen for the purposes of iilustration and description as shown in the accompanying drawings wherein:

In the following description and in the claims various details will be identified by specific names for convenience; these names, however, are intended to be generic in their application. Corresponding reference characters refer to like members throughout the several figures of the drawings.

The drawings accompanying, and forming part of, this specification disclose certain details of construction for'the purpose of explantion of the broader aspects of the invention, and that the invention may be incorporated in other structural forms than shown.

in the'down position of FIG. 2, or the up position of FIG. 3. When a deck 10 is provided the outer end of this deck is retained by an extrusion 50 which is similar in configuration to the'F-shaped member 12 except that the downwardly extending leg isdisposed at a slope inwardly at about thirty degrees. This downwardly extending leg has a hole 51 therein which provides means for attaching as by a bolt 52 the leg to a brace post 54 which has aligned cooperating holes 56 formed therethrough in opposite side walls. A hole 58 in the lower bar of extrusion 50 is adapted to align with a hole 60 in deck 10. A bolt or rivet 62 is passed Description of the Preferred Embodiment of FIGS. 1,

2and3 Referring now to the swimming pool frame construction as seen in FIGS. 1, 2 and 3 there is depicted the framework for an above ground swimming pool having an upper deck identified as 10. This deck may be made of aluminum extrusions usually of U-shape or as a solid planking. These members are supported at both ends by appropriate aluminum or like metal extrusions. The inner end of the deck 10 is retained by an extrusion 12 which also forms the front coping. As shown, this extruded member is an F-shaped piece with its upper horizontal bar portion made shorter in length than the lower horizontal bar portion. The space between these horizontal bars is sized to slidably receive the ends of deck member 10. The downwardly extending vertical bar provides the inward face of the coping providing the protection and concealment of the upper end of a flexible liner 14 and a sheet metal wall member 16. A plastic U-shaped clip 18 conventionally grips and retains the liner 14 against and to the wall member 16.

. Regularly spaced around the pool frame whether the pool is made round, rectangular or polygonal are uprights 20 which are shown as rectangular or square hollow extrusions. Slidably and removably carried in these uprights are T-brackets 22 which are disposed to support the deck 10 and also the coping front 12. In the upper bar portion of thisv bracket 22 are formed two holes 24 which are spaced and sized so as to mate with a hole 26 in shown deck 10 and with the other hole 24 with a like hole 26 as provided him adjacent deck member 10. A hole 28 is formed in the lower horizontal bar of member 12 and is used with upright 20 to position the bracket 22. A rivet or bolt 30 is passed through alignedholes 26, 24 and 28 and is tightenedto secure the deck 10 to one end of bracket l2'and one end of T-bracket 22.

Also formed in the downwardly extending legs of the T-bracket 22 are aligned holes 32 and 34. A pair'of aligned holes 36 are formed in opposite side walls of upright 20 and bolt 40 and nut 42 is used in the holes 36 and in either hole 32 or hole 34 to retain bracket 22 Use and Operation of the Frame Assembly of FIGS. 1,

2 and 3 Y Toassemble the pool frame workmen arrange and connect a bottom ring or frame, not shown, and to this frame uprights 20 and diagonal brace posts 54 are attached. The new deck or coping and the method of at tachment to this assembled frameprovided by this invention enables the metal side wall 16 to be made longer than is presently customary with prior procedures. This liner supporting wall 16 and the plastic liner 14 with which it is associated may be made as long as the upright 20 which permits, in the present invention, a filled heightof the pool which is approximately two inches more than has normally been available in prior known pools. The workmen arrange and assemble the frame and the uprights 20 and brace post 54. The deck 10 is then secured to the uprights 20 and brace posts 54 by T-brackets 22 slidably retained within the formed interior of the uprights 20 and selectively movable up and down therein. Extrusion 50 is bolted to posts 54 with the pool frame and posts assembled but without the liner l4 and the metal wall 16. The plurality of workmen normally required to assemble the pool'may then be dismissed since only one person is needed to complete the assembly of the pool and install the water therein.

The metal liner walls 16 are placed in position against the supports 20 while and when the coping front 12 is lifted, the semirigid deck permits the coping front 12 to be brought to the condition of FIG. 3. A bolt 40 is pushed into and through the holes 36 in' the upright and also through holes 32 in the T-member 22 to maintain the deck 10 and the coping front 12in the position of FIG. 3. After the metal liner l6 and the plastic liner 14 have been arranged and smoothed to the condition decap 18 is applied to retain liner 14 and wall 16 in the I selected position. The deck 10 and the front coping 12 are now lowered by removing the several bolts 40 permitting holes 34 to be brought into alignment with holes 36 whereupon the several bolts 40 are reinstalled. A nut 42 is installed on and tightened on each bolt to cause the top deck 10 and the front coping 12 to bese'cured in the pool use position.

To replace, repair or rearrange a flexible lining 14 it is only necessary that a workman'remove the nut 42 and bolt 40 and lift the deck 10 upwardly to bring the hole 32 in the T-bracket 22 into alignment with hole 36 in upright 20 whereupon the bolt 40 is re-installed to maintain the deck 10 and front coping 12 in the condition of FIG.:3 and in this position permitting easy ac- T-bar 22 are the holes 32 and 34 as in FIG. 1.With the through hole 36 and the hole 34 in the T- bracket 22.

It is to be noted that on the outer extrusion'support 54 there are provided two holes 56, one of which is adapted to engage and support one of the rear extrusions 5.0 and the other hole will retain an adjacent like extrusion and an adjacent deck member in a like manner. One of the holes 24 in T-bracket 22 is adapted to mate with one hole 26 of the deck 10 so that one T- bracket 22 will retain two deck sections 10 and will secure and retain the ends of adjacent coping front members 12.

Alternate Embodiment of FIG. 4

Referring next and in particular to FIG. 4 his to be noted that instead of a back brace post 54 which is disposed to extend all the way to the bottom ring or retaining brace it is contemplated that a back brace 154 is disposed to engage upright 120 intermediate its ends. Upright 120 like upright is disposed to receive a front coping l2 and a T-bar 22 as in FIG. 2. In like manner wall member 16 and flexible liner 14 are similar to those shown in FIG. 2, however, back brace 154 although similar to brace 54 of FIG. 2 in the embodiment of FIG. 4 is formed with a clip portion 155 which is disposed to slidably engage the upright 120 and is slidable up and down on post 120. A bolt 40 engages either hole 157 or 158 formed in bracket 155 and is brought into alignment and through a pair of holes formed in opposite walls in upright 120. To secure the bracket 155 in the desired protective position as in FIG. 4 the hole in leg 120 is brought into alignment with hole 157. When the deck 10 is to be lifted the bolt 40 now in hole 157 and in through the pair of receiving holes in the upright 120 isv removed as is also a bolt 40 through the pair of holes 136 in upright 120; The deck 10, the front coping l2 and the support leg 154 is now moved upwardly to bring holes 132 and 136 into align ment. At the same time hole 158 is brought to the height previously provided by hole 157 and a bolt 40 is placed through these aligned holes. When the hole 32 in T-bar 22 is brought into alignment with hole 136 in the upright a bolt 40 placed therethrough causes the deck 10 and front coping 12 to be-raised to determined distance sufficient to bring this front coping 12 to a position similar to that as seen in FIG. 3. In this position the liner l4 and support wall 16 may be replaced, repaired or otherwise adjusted. After the desired repair has been completed the bolts 40 are removed to permit the deck 10 and front coping 12 and rear brace 154 and bracket 155 to be brought to the lowered condition now seen in FIG. 4. The bolts 40 are now reinstalled and with nuts 42 are tightened to maintain the deck and coping in the desired use arrangement.

Alternate Arrangement of Coping as Seen in FIG. 5

coping 212 raised and supported by bolt 40 in aligned holes 36 and 32 the wall 16, liner l4 and clip 18 are ex posed and available for manipulation by a workman.

With the bolt 40 in holes 36 and 34, the coping 212 protects the'assembled wall 16, liner l4 and clip 18 as in the assembled condition of FIG. 5. When the coping 212 is in the raised condition the clip 18 and the upper Embodiment of FIG. 6

Referring finally to FIG. 6, it is to be noted that the scope of the invention also includes raising both the upright 20 and an attached coping to expose the side wall 16 and the flexible liner 14 and the attaching clip 18. Assuming that the wall 16 is in an unattached condition to the side'frame it is to be noted that the coping as an attached upright may be moved if as a part of a bottom ring member 300 there are upright clips 302 attached to this ring. These clips are formed with 'a hole 304 which is used to establish the upper limit engagement for an upright 306 having two pairs of vertically spaced holes. This upright tubular member has two pairs of I holes 308 and 310 so spaced that when the lower hole 308 is in alignment with hole 304 and a bolt 40 is placed therethrough the side wall support is maintained in a lifted position as shown in FIG. 6. The upper hole 310 when brought into alignment with hole 304 and bolt 40 is inserted and the upright 306 is maintained in its lower position. A bolt similar to bolt 40, as seen in FIG. 1, is adapted and is used to secure the upright 306 in either of the two desired positions by merely placing the bolt in thedesired aligned holes 308 or 310 and tightening by a nut 42. i

The upright 306 when in the raised condition lifts and retains the attached coping member from in way of the clip 18, the liner l4 and the side wall 16 to permit installation and easy repair. It is assumed that, of course, a coping similar to coping 212' as seen in FIG. 5 or a coping l2 and deck 10 as in FIGS. 1 or 4 will be used, which coping when upright 306 has been brought down into its bottom secured position and the bolt 40 placed through holes 304 and 310 will cause the coping to enclose and protect the edge of the assembled side wall and liner.

In all the above embodiments of FIGS. 1 through 3, as well as the embodiments shown in FIGS. 4, 5 and 6, it is to be noted that a removable fastening member preferably in the form of a bolt 40 and nut 42 is used to retain a coping in one of two elevated positions. It is to be further assumed that the swimming pool of this invention will utilize a flexible wall of some sort and a waterproof liner which wall and liner are secured at the top of this flexible wall by means such as clip 18. In its fully assembled and used condition a coping or some similar type of cap piece covers this upperedge and protects the clip piece 18 and the assembled upper edge of the liner and the wall used therewith. In its assembled condition both the liner and supporting side wall may be brought to the extreme'top of this support frame as'exemplified by upright 20 which provides a higher level of water in the pool in relation to the side wall assembly than with-the water retaining means of swimming'pools providedprior to this invention. Torepair, replace or install a liner 14 and/or a portion of a complete supporting side wall 16 of a pool it is only necessary in practicing this invention that the retaining bolts 40 by which the T-bar members and the like by which the cap or base ring are secured to the uprights be removed and that the coping protecting member which selectively conceals the clip 18 and the secured ends of the liner and wall be uncovered by lifting the coping to a height slightly above the assembled condition. In this elevated condition the clip 18, the liner l4 and the wall 16 may .be separated and easily removed or rearranged within the swimming pool.

The improvements, above noted, of being able to extend the effective height of the swimming pool by two inches or so without the use of additional materials is, of course, an obvious advantage provided by this pool frame assembly. Another important improvement provided by this invention is that the liner 14, the usually used metal retaining wall 16 and the retaining clip 18 or a similar means may be installed and manipulated for repair or replacement by only one workman; This is an important improvement in that during the filling of the pool necessary changes in thearrangement of the wall 14, the liner l6 and its securing member 18 may be manipulated-by only a single workman who may only need to locally raise the coping. This is accomplished by removing the bolts 40 and securing two or three sections of the coping in a raised condition sufficient to permit the upward moving of the coping and exposure of the joining member, the retaining clip 18, the wall 16 and the liner 14.

Although T-bar 22 is shown as having two vertically disposed pairs-of holes 32 and 34 and upright with only one pair of aligned holes 36 the opposite arrangement, of course, could be used. In addition the T-bar 22 need not have its downwardly extending portion sized to fit within extrusion 20 but'other configurations such as making upright 20 as an angle or T-bar member and member 22 as a member whose downwardly flat leg is disposed to lay against the upright member and by appropriate holes be secured by a bolt and nut. Tongue and groove means, pins and notches and the like may also be formed in the upright and the mating coping member to provide a two height support means for the coping. The economies in the design of the upright and the coping and attachment as well as the pool configuration dictates the construction to be used. The

dual height provision of the coping protective member and the ready adjustment to these two heights by one workman is the contribution to the flexible liner swimming pool construction provided by this invention.

Method-of Repairing and Installing a Flexible Liner in a Swimming Pool The present invention also provides an economical and easy method for one workman to move the coping from its protective position to an above height whereat the means for securing of the flexible liner to the support wall is exposed enabling work on the liner or wall to be accomplished. The method of the maintaining and supporting a coping at two selected heights includes the steps of: (a) forming the uprights by which an associated coping member is cooperatively supported and retained with at least one securing and positioning means such as a hole; (b) forming on the cooperative means of the coping at least one securing and positioning means disposed to mate with the securing and positioning-means on the upright so as to provide one height relationship of the coping to the top of the upright; (c) forming an additional securing'and positioning means in one of the cooperative portions providing the retained support of the coping on the upright, this additional securing and positioning means providing a vertical displacement of the coping which is a short distance from the first position, and (d) inanipulating the securing and positioning means on both the coping and uprights to position and secure the coping in a protectiveand concealing position above the means for securing the top of the liner to the side wall and with a further manipulation to release the coping from its protective and concealing lower position to a supported condition a short vertical distance above the means for securing the flexible cover to the side wall, the coping in this vertically displaced position exposing the means for the securing of the liner so that said means may be released for the replacement, repair, rearrangement and the like of the liner without disassembly of the pool frame.

In the above description the coping and deck have been shown as two separate members. It is, of course, possible for a deck to be made as a unitary member with a downwardly extending inner lip which would protect the securing of the side wall and the flexible liner. It is also to be noted that instead of separate uprights a heavier side wall could be used which would serve as the upright and to this wall a coping be atvided within the scope of the invention which is to provide a protective member for the securing of the liner to the side wall and then to selectively lift this protective member to expose the retaining means for the liner to the wall.

Terms such as left, right, up, down, bottom, top, front, back, in, out and the like are applicable to the embodiments shown and described in conjunction with the drawings. These terms are merely for the purposes of description and do not necessarily apply to the position in which the swimming pool and its coping member or framework may be constructed or used.
